Re: Winter project..see-through hatch boards

Too bad you used Lexan. It fogs up completely in three years, and after that , you wont be seeing much thru it. That will give you your privacy back.

Re: Winter project..see-through hatch boards

That will happen despite the fact that there's a Sunbrella cover over the boards when it's berthed, will it?

"but OTOH they look like something that an owner could make with some thought and time..."

Pictures of one of my prior winter's project.... lock hardware attached since these pics. Made from 1 inch teak planned to 7/8 inch thick.

True in general, but perhaps not as bad as stated....
Our original fixed ports were Lexan. Badly "fogged" when we replaced them in '95. The first owner had never (!) taken care of them at all.

Deciding that there was no reason to doubt the original engineering specs, we replaced with Lexan, even knowing it's reputation for hazing.

BTW, there are surface coatings/layers nowadays commonly applied to Lexan that much reduce the hazing.
(We needed to properly rebed all the lenses anyway, due to leaks un-addressed by the prior owner.)

Anyhow, to make a long story slightly shorter, we installed them with the proper sealant, at the proper depth, and they are still clear... and... leak free.

That is, clear for about two months at a time after I polish them out and overcoat/buff them with Plexus.
So, they will indeed get hazed up if neglected, but the neglect is not required.

Best,
LB

ps: note that even smoked Lexan (or acrylic) - with some hazing - will be disturbingly transparent from the outside at night to passers-by on the dock...... even though you cannot see out from the inside of a lighted interior.

pps: CCHER, Nice Looking carpentry!!

Re: Winter project..see-through hatch boards

I wonder if 303 Protectant works on Lexan?

Really nice job on the hatch boards. Adding automotive tint over plastic might not be the best way to go. It tends to get bubbles under the tint after a while.

Re: Winter project..see-through hatch boards

CCHER, nice job on your doors as well. Once you have a set of doors you'll never go back to hatch boards.

Re: Winter project..see-through hatch boards

We made doors on a previous boat but used 'lift off' hinges.. could still put them away when required. Dealing with the open doors while sailing can be inconvenient.

CCHER, do your doors still lift out? Indeed, nice work!

No but 4 screws on each of the stainless hatch board holders and they're off and I could go back to hatchboards if conditions ever called for it. I'm a coastal cruiser and weather adverse so hopefully I won't get in that extreme situation.

[Once you have a set of doors you'll never go back to hatch boards.]

Agreed, I had doors on my old boat and this was one of my first projects on my new one after one season with the hatchboards.

Re: Winter project..see-through hatch boards

Covering them helps a lot, but eliminates the advantages of being able to see thru therm. White Sunbrella will still let a lot of light in,( and some UV).
Friends left BC with the hard surface Lexan. By the time they got to Frisco ,the hard coating had fallen off like old varnish, and they spent the rest of their Pacific circumnavigation looking thru foggy windows. Didn't matter from Japan to BC, as it was so foggy they only had 2 days out of 40 without fog. The rest of the trip, they couldn't see the bowsprit from the cockpit. They switched to plexi as soon as they got home.
